It always sounds strange to my ears when I see this kind of list in June! We have half of 2016 to happen and people are already declaring things for the whole year, as if it had already finished.
But here we have another list of the top programming languages in 2016:
It includes an image, with data extracted from indeed.com:
Good news is that Ruby and Rails are there. Bad news is that they are in the last position! But don't despair, because we have this other list, extracted from http://tiobe.com. This one is updated till this month and if you want to go there to see for yourself, this is the link.
As you may see, Ruby jumped from the position 16 to the position 10! This is really good news.
On the other hand, languages like C#, Objective-C, Delphi/Object Pascal and COBOL are going down every new month. A good message for those who intend to spend time and money with them: Don't do it! Pick another language!
